Hélène Smith was a colorful character.
She was a medium who was studied in 1891 by a psychologist because of
her supposed ability to predict the future, channel entities, have dramatic
play-like conversations with people no one but her saw and move objects
with her mind. She also claimed to be able to speak and write Martian.
So of course it was decided she was "nuts".

During her trances she would write descriptions of Mars,
an example of which is above. The psychologist who studied Hélène
in depth said that she had suffered most of her life from "daydreams
that bordered on hallucinations" and a "dissociative personality"
but that some of her abilities seemed to be genuine. He also stated
that the "Martian" seemed to be modeled on the French language
and a product of her subconscious.
